xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files


   xzcmp [cmp_options] file1 [file2]
   xzdiff [diff_options] file1 [file2]
   lzcmp [cmp_options] file1 [file2]
   lzdiff [diff_options] file1 [file2]


   xzcmp  and  xzdiff  invoke  cmp(1)  or diff(1) on files compressed with
   xz(1), lzma(1), gzip(1), bzip2(1), or lzop(1).  All  options  specified
   are  passed  directly  to  cmp(1)  or  diff(1).   If  only  one file is
   specified, then the files compared are file1 (which must have a  suffix
   of a supported compression format) and file1 from which the compression
   format suffix has been stripped.  If two files are specified, then they
   are  uncompressed  if necessary and fed to cmp(1) or diff(1).  The exit
   status from cmp(1) or diff(1) is preserved.

   The names lzcmp and lzdiff are provided for backward compatibility with
   LZMA Utils.


   cmp(1), diff(1), xz(1), gzip(1), bzip2(1), lzop(1), zdiff(1)


   Messages  from  the  cmp(1)  or  diff(1)  programs  refer  to temporary
   filenames instead of those specified.
